CAMP CHAIR.

Application filed March 30, 1921.

To. all whom may concern:

Be it knownthat. I, Anonr VICTOR TESTER, a citizen of Sweden, residing at Bristol, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Camp Chairs, of which the following is a specification.

My invention relates to. improvements in camp chairs, and the object of my improvement is. simplicity and economy in construction and convenience and efficiency in use.

. My inprovecl camp chair comprises frame that comprises a pair of mating side structures 10, each of which-side structures 10 is made of a pair of frame pieces 11 that are crossed adjacent the middle and are pivotally connected, as by a pin 12, substantially in the usual mannenthe seat 13, made of fabric, being supported fror-n the upper endportions 14 of frame pieces 11 in aspecial manner, to be described.

The opposed side structures 10 are crossconnect-ed at each end-of the chair structure by a collapsible brace structure 15 made of crossed strips 16 of sheet metal, pivotally connected at the junctionl? by a pin, and having theends 18 perforated for engaging with a connecting eye 19 of suitable form that isv mounted on the frame pieces 11 in any suitable manner, the latter being made of Serial No. 456,827.

wood, as usual. A symmetrical and balanced structure is Obtained by constructing and ar1-a1-1ging .the parts so that the two inner frame pieces 11 swing back and forth in parallelism and the two outer frame pieces 11 also. operate similarly and in unison. To permit of'this being donethe crossed metal strips 16 of the collapsible brace structure 15 are each provided with a slight though appreciable lateral kink or bend at some point intermediate the pivotal connection and one of the ends, as shown in Fig. 2 and particularly in Fig. 10. This latter expedient serves to permit of locating the pivotal connections 17 for the brace structures 15 at the same height from the floor as the pivotal pins 12 for the frame pieces 11, and thus facilitates the collapsing and opening of the camp chair structureas a whole.

The seat- 13 has the ends secured by suit able nails or tacks 20 to a crossbar 21 of Wood that has adjacent each end a special form of structure that is adapted to cooperate with thespecial form that is provided for the upper end portions 14 of the frame pieces 11, so that these parts can be connected and disconnected at will and when connected will effect a relativelyfirm and effective conn ection.

As shown, the said upper end portions 14 have each. a forked form, comprising a re cess or slot 23 that separates a pair of fingers, comprising the outer finger 24 on theoutside and'the inner finger 25 at the inside.

The bar 21 has a cross-slot 26 across the lower edge portion 27 of appreciable depth and of a width such as to be adapted to receive and fit over the part of the upper end portion 1% with whichit engages so as to position the side structures 10 relatively one to the other in the longitudinal direction of the bar. In extension of the cross-slot at the rear, the bar 21 is cut away, as shown at 28, so that the remaining,-uncut portion 29 is-a fit for and adapted to be received into the slot 23 of the forked upper end portion In use the said uncut portion or reduced portion 29 of the bar 21 is limited in the downward movement by being seated on the bottom or end wall of said slot 23. As shown, the end wall of said slot 23 is rounded;

in semi-circular form and the bottom Wall of said reduced portion 29 that cooperates therewith is also rounded so as to approximately fit the same.

The extension 28 of the cross-slot 26 is in the form of a slot at the outer portion of the bar 21 that fits against three faces of the outer finger 24, comprising the inner face that is covered by the reduced portion 29 and the two adjacent side faces, the outer face of said finger 24 being exposed and uncovered so far as concerns material of the bar 21.

As shown, however, said extension or outer slot 28 is formed into a closed socket thatfits the outer finger 24 by a closure in the form of a strap 30 of sheet metal that extends as a bridge across the open portion of said outer slot 28 and is secured by its ends to the outer face of the bar 21 by means of nails or other suitable securing devices 31, said strap30 being adapted to bear against the outer face 32 of said finger 24.

As described, the joint between the individual upper end portions 14 of the frame pieces 11 and the cooperating ends of the cross-bars 21 comprises in each case the closed socket 28 on the bar 21 in which is housed the outer finger 24, a shoulder-like seat provided by the'end wall of the slot 23 in the frame piece 11 on which is seated the reduced portion 29 of the bar 21, and

I the bottom cross-slot 26 at the lower edge portion 27 of the bar 21 in which is housed the part of the upper end portion 14 of the bar 21 that is immediately below the slot 23, and the outer finger 24. Said part of the bar 21 comprises the part of the body 9' portion of the bar 21 that is adjacent the slot 23 and the finger 24.

hen set up for use the frame proper comprises the two cross-bars 21 as a part thereof. These serve as locking devices for the other part of the frame structure that is composed of the four frame pieces 11 and the two sets of end brace structures 15, constructed and arranged as described. Thelocking effected by said cross-bars 21 is such that said frame proper or complete frame is rigid and firm and does not yield in any direction, other than such slight movement as may be had due to the resiliency of the materials.

All of the elements described cooperate to effect this result.

In the modified form of structure shown in Figs. 6, 7, 8, and 9 the seat 13 is supported by a pair of end bar structures 21 that are formed each of a rod 33 on the middle and major portion of which is mounted a piece of metal pipe or tubing 35 that receives the end portion of the seat 13 The socket structure at the ends of the rods 33 in each case is formed by means of a U-shaped sheet metal loop 36 that has the side arms 37 perforated and mounted on the end portion 38 of the rod 33 that extends beyond the seat supporting tube 35 and provides a space 28 intermediate the said end portion 38 and the yoke portion 39 that is a fit for the outer finger 24, as in the case of the socket 28 described above.

The tip ends 40 of the rods 33 are headed over to hold the loops 36 in place.

Considering the details of the reduced portion of the cross-bars and the adjacent parts, by providing a single groove or slot 28 only and having this on the outer face, the solid, uncut portion 29 thereof is an integral part of the inner side portion of the bar, which is continuous and uninterrupted. Thus a single plate 30 serves to change the groove or slot 28 into a closed socket that is adapted to enclose one of the fingers on the leg. Also, the outer finger is used'for co operating with the socket.

Among the advantages that follow from the construction described it will be noted that the fabric structure of the seat 13 is made longer; an uninterrupted bearing edge for the seat is provided along the upper, inner corner of the bar 21; the closure for the socket 28 is on the bar itself; and the resistance to tension due to a load on the seat 13 is sustained by the rear or outer finger 24 and the bottom of the slot 23 in the leg 11, and generally independent of the inner finger 25. 1

By having the hinge connections for the cross-braces 16 on the outer edge portions of the legs 11 the latter can be folded into a compact bundle, as shown in Fig. 10, with the adjacent legs in face to face contact by their opposed faces.

I claim as my invention 1. In a camp chair, a pair of side structures positioned in spaced relation, said structures being formed each of a pair of crossed and pivotally connected frame pieces, a collapsible brace structure serving to interconnect said side structures, said frame pieces having each at the upper end portion a shoulder-like seat and an outwardly directed finger adjacent said seat, a pair of cross-bars for extending across the space between said structures, and the end portions of said cross-bars having closed sockets that fit over said fingers and are adapted to be received thereover, with part of the border wall of said closed socket engaged with said seats.

2. In a camp chair as described in claim 1, said brace structure being in the form of a pair of crossed and pivotally connected metal strips, the ends of said strips being individually connected by a hinge connection to the different frame pieces, and said hinge connections being constructedand arranged so as to be confined to the outer edge portions of said frame pieces, whereby the opposed faces of the frame pieces will be said members and bars comprising a finger free and unobstructed. on the member and a closed socket on the bar 8. In a camp chair comprising a frame for enclosing said finger, said socket being 10 structure having a pair of opposed side in the form of a slot in the material of said frame portions that are composed of crossed bar with a closure in the form of a strap of members and a pair of cross-bars for supsheet metal. porting the seat, and the joints connecting ADOLF VICTOR VVESTER.
